Updated src/settingswindow/imp.rs:

- Updated reuse copyright year
- Added clearer import headers
- Refactored to now import std::cell::OnceCell as it has been [merged into std](rust-lang/rust#105587)
- Refactored to now import std::sync::OncelLock as it has been [merged into std](rust-lang/rust#105587)
- Refactored to import Value from glib::value as it now has its own module in glib
- Refactored to import Variant and FromVariant from glib::variant as it now has its own module in glib
- Added glib::BorrowedObject import
- Refactored to use glib::signal::Propagation instead of glib::signal::Inhibit
- Refactored "properties()"function to reflect OnceLock changes
- Removed now unused "_obj" parameter to "property()" and "set_property()" functions
- Removed deprecated "window" parameter from "close_request()" function
- Updated "close_request()" function to return a Propagation type
- Updated "parent_close_request()" call in "close_request()" function
- Refactored "constructed()" function to get "obj" reference via "self" instead of as a parameter
- Updated "parent_constructed()" call in "constructed()" function

Updated src/settingswindow/mod.rs:
- Updated reuse copyright year
- Added clearer import headers
- Updated "new()" function to use "Object::builder::<SettingsWindow>().build()" instead of untyped "Obect::new()""
